Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed December 3,, 1915. Serial No. 64,894.

To all whom it may concern:

Be it known that I, J oNAs THEODOR LAGER- GREN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Water-Purifiers for Ice-Making,for a type of which the following is the specification.

My invention relates to improvements in water. purifiers for ice making machines and the object of'my invention is to provide means for preventing ice having a cloudy appearance caused by air, gases and other foreign matter contained in the water before freezing, and .it consists essentially 'of a container, filtering material therein through which the water passes, an overflow, means for breaking up theoverflow into fine portions, a vacuum pipe connected tothe container, and a receiving tank connected to the container and to the vacuum pipe.

Figure 1 is across-section through my device. Fig. 2 is an enlarged plan View of afragmentary portion of my device for breaking up the overflow, the top being removed and the container shown in cross-section.

Fig.3 is an enlarged view of a fragmentary top being removed and the container shown in cross section.

Having described the principal parts involved in my invention, I will briefly describe the operation of the same.

The water enters through the supply pipe 1 into the interior of the cylinder 18 and then filtering through the filter material 20 passes under the lower edge of the cyl1 n der 18 and up through the filter material between the cylinders '16 and 18. As the water overflows the cylinder 16 it runs into the tray 21 and through the holes 22 thereof into the filter matter between the cylinders 16 and 14. Then the water passes under the lower edge ,of the cylinder 14, up through the filter material and overflows the cylinder 12 into the tray 23 and through the holes 24 thereof into the filter material between the cylinders 10 and 12. From thence it passes under the lower edge of cylinder 10 and overflows into the tray 25 and through the holes 26 thereof. The holes 26 are so placed as to be over the ledge 3 and as the water drops from the holes onto the ledge any air contained in the waterwill be. separated therefrom and pass off through the Vacuum pipe 7. The water then goes down between the containers 3 and 9 and off through the pipe 30 to the freezing can 27. The filtering material 20 may be wood shavings, charcoal or any other suitable material. During the operation a vacuum pump connected to the pipe is kept working and as the air or other gases rise to the top of the filtering material and is liberated by the water dripping through the holes in bottom of the trays and splashing on the ledge 3", it passes off through the vacuum pump. As the receiving can 27 is also connected to the vacuum pump by the pipe 32 no air can become mixed with the water entering it and so the water is kept free of air or other gases. To obtain the best results the water in the container 3 should be kept below the level of the ledge 3 and this is regulated by the stop cocks 2 and 31. The vacuum is regulated by the cocks 8 and 33.

Thefreezing may take place in the can 27 as shown connected to the filtering con tainer or the can. 27 may be separated and placed in a freezing chamber and another similar can or other vessel attached to the top 28 which is permanently connected to the filtering container. A. permanent vessel with proper inlets and outlets and with mom um connections may also be placed between the filter container and the freezing can proper.

As an alternative construction in place of the trays with holes therein,'in the modified.

construction shown in Fig. 4 the water trickles through the angular notches formed at the base of the saw teeth as through the holes 22, 24"and 26. The saw teeth v37 of the shelf 36 are so placed that the water trickling therethrough will fall on the ledge of the container 3 the same-as through holes 26.

Hence it will be seen that I have devised simple means for filtering and removing air, gases and other foreign particles from water before freezing thus insuring a pure clear ice. The water when entering the fil- .er container may or may not have passed through any previous stage of filtering or chemical purification.
